Abstract (en)
The present invention relates to a negative electrode active material for a lithium secondary battery, a negative electrode including the same, and a lithium secondary battery including the negative electrode. Specifically, the present invention relates to a negative electrode active material capable of minimizing changes in a structure and internal total pore volume of an electrode during rolling of the electrode by controlling the type and amount of carbon coated on a surface of an artificial graphite active material, a negative electrode including the same, and a lithium secondary battery including the negative electrode.
